1. Why wasnt a beta-blocker tested as first-line therapy?
2. Reasons for no beta-blocker arm Feasibility considerations allowed only 3-4 arms--traditional drug(s), ACEI, CCB, +1?
Traditional drug choices considereddiuretic, beta-blocker, or either/both.
Most hypertension trials used diuretics.
Pooled results of 3 older diuretic vs. beta-blocker trials showed no CVD differences.
(Collins et al. Lancet 1990;335:827-38)
3. Reasons for no beta-blocker arm(continued) Concerns about beta-blockers in patients with diabetes (oversampled in ALLHAT), although UKPDS results (atenolol vs captopril) subsequently lessened concerns (BMJ 1998;317:713-720).
Pooled analyses of 18 trials ?low-dose diuretics but not beta-blockers prevent first
CHD events (Psaty et al. JAMA 1997;277:739-45).
